Cook dinner myself for cheap, or order a takeaway?
Spend an hour cleaning the apartment myself, or pay for a cleaner, and use that hour to read a book? How much would I need to get paid to spend a Saturday on a work project?
You face these questions every day. And, whether consciously or not, you do make decisions about them. But, how do you know that the choices you make are good?
The only way to know would be to quantify how much an hour of your time is worth for you. Luckily, there is a tool that helps you quantify that. And, based on the responses people share in it, we can learn a lot more about the relationship between work and the value of our time. …
Data analysis is just one fun thing to do on a weekend, but what’s way more fun is to play a fortune teller. That’s the feeling* that leads some strange people (well, I know at least one) to decide to self-study machine learning. 🤷♀️
These people try to apply models to everything they encounter. And in this post one of such ML newbs is fighting with a dataset of tweets to answer the question:
How can we use existing Twitter data to make predictions about future tweet engagement?
Join this thrilling quest!
I’m a self-learning beginner in ML. Most of my decisions in how to approach the problem below are based on online courses and tutorials I happened to have taken. While I tried to make informed decisions about what I’m learning and where (shoutout to DataCamp Team & Dataquest) there is high margin of error in the choice of process and the results. If there is a standardised, state-of-art way of approaching this kind of problem, or of the below makes no sense, let me know! …
How much is an hour of your time worth? You can look at how much you earn. But, if someone paid you 2 times more per hour would you sacrifice an hour of your free time to split the good and bad lentils like Cinderella?
The worth of your time is not just how much you’re paid. You know it and, consciously or not, you assign a value to your time and based on this evaluation you make choices in life.
It’d be preferable to make better-informed decisions about how to spend your time. …
As if bacteria in the bananas wasn’t enough, there was also a lemon ritual.
We’d drink tea with lemon and sugar. But, before cutting the lemon you had to pour hot water over it.
Not just hot water from the tap. You had to boil water, place the lemon on a heat-resistant surface— like the side of a kitchen sink—, and pour the steaming water over the fruit, making sure each side has been poured over.
Mum did it and, after I was old enough to use a gas stove to soft boil an egg, I did it too.
Why though? Because of the viruses and bacteria on tropical fruits coming from other continents full of deadly disease — that’s why! Sigh. …
Everybody knew it was not wise to eat the end of a banana. How big of a piece they would leave was their discretion.
Somehow, a belief was constructed that there is a particular species of an African fly that lays eggs in the end of the bananas.
(Don’t ask how, let’s leave this as one of the mysteries of the 90s in Eastern Europe.)
Let’s assume for a moment it was true, as a mind of a 9-year old did.
The obvious consequence of eating the end of the banana was exposing yourself to the risk of eating flies’ eggs, which would then, naturally, hatch in your stomach. A simple cause and effect reasoning. …
I put a fake tomato on the scales. The plate goes down. So far so good.
The lower the item drops the more it weighs, I reason. Isn’t that what Newton was about?( — a 7-year old Marta never thought, but wishes she did, because it’d make for a good story.)
I see other kids are putting cylindrical blocks on the other plate of the scales.
Well now, that’s mysterious.
I’ve already concluded most of them were morons, based on yesterday’s inability to solve for 2(2+3), but such a unified display of moronism? Suspicious.
I observe the following:
a) They are not taking the tomato off first. This makes no sense to me. How can you try to weigh two things at the same time? …
